Poly(lactic acid) or polylactide (PLA) is a biodegradable, thermoplastic, aliphatic, ployester derived from renewable resources, such as corn starch(in the U.S.) or sugarcanes(rest of world). Although PLA has been known for more than a century, it has only been of commercial interest in recent years, in light of its biodegradability. The name "polylactic acid" is to be avoided, not complying to standard nomenclatures (such as IUPAC) and potentially leading to ambiguity (PLA is not an acid). It can be used to make toys, textiles, and plastic products.
